Similar to the nar-info disk cache (and using the same db). This makes rebuilds muuch faster. - This works regardless of the ca-derivations experimental feature. I could modify the logic to not touch the db if the flag isn’t there, but given that this is a trash-able local cache, it doesn’t seem to be really worth it. - We could unify the `NARs` and `Realisation` tables to only have one generic kv table. This is left as an exercise to the reader. - I didn’t update the cache db version number as the new schema just adds a new table to the previous one, so the db will be transparently migrated and is backwards-compatible. Fix #4746
